Parts of Rockhampton are starting to go under, while final preparations are being put in place in other areas, as the Fitzroy River slowly climbs to its predicted peak of nine metres.
The river had risen to just under 7.8m by midday Tuesday, and is now expected to peak on Thursday morning, when about 3000 homes and businesses will be affected.
Low-lying suburbs like Depot Hill are due to be inundated but authorities have installed flood mitigation measures, including floodgates on stormwater drains, as well as a new system of temporary levees, on the north side of the river around Beserker.
However, even that has its drawbacks, with the levees running down the middle of suburban streets, meaning only one side is protected.
For 27 years Barb Reid has lived in her Berserker house, which is now on the wrong side of the temporary levees.
She said the area regularly floods, either from flash flooding or when the river rises.
Ms Reid rode out Cyclone Marcia in 2015 in her bathroom, an event which she said was more concerning.
"We're used to floods in Rockhampton, it's the cyclones we don't like, we'll take a flood any time."

She said she was concerned about what effect the levees would have on the flood level but said they had been in contact with authorities and had been assured everything would be fine.
The water is expected to stay up over the weekend after it peaks, before eventually subsiding by next week.
Meanwhile, A kangaroo has been killed by a car in the Rockhampton CBD after the animal tried to escape from floodwaters.
The roo was hit on Quay street, next to the Fitzroy river, with witnesses saying it was jumping erratically across the road.
